GUI problems/freeze when used within KDE

[Michael Goffioul]

Jacob,

On my F16 I'm using KDE as desktop environment. However I have various problems when using the file dialogs (it appears Qt is using the KDE standard file dialogs when run from a KDE desktop):

1) the first time a file dialog is shown, the whole GUI freezes for about 2 minutes (see backtrace below)

2) when it gets back, I see this in the terminal widget:

KGlobal::locale::Warning your global KLocale is being recreated with a valid main component instead of a fake component, this usually means you triedto call i18n related functions before your main component was created. You should not do that since it most likely will not work

QProcess: Destroyed while process is still running.

QProcess: Destroyed while process is still running.

3) the file dialog does not stay on top on the octave GUI window

When the GUI freezes in 1), the (partial) gdb backtrace is as follows:

I'm a bit puzzled by the KSambaShare bits...
